【摘要】 从中国南海高领类尖柳珊瑚(Muriceides collaris Nutting)中分离得到了7个愈创木烷型倍半萜:1个新化合物6-formyl-5-isopropyl-3-hydroxymethyl-7-methyl-1H-indene(1)、1个新天然产物5-isopropyl-3,7-dimethyl-1H-indene-1-one(2)及5个已知化合物:guaiazulene(3)、4-formyl-7-isopropyl-10-methylazulene(4)、sesquiterpene ketolactone(5)、alismoxide(6)和guaia-1(5),6-diene(7)。化合物的结构通过现代波谱技术[MS、IR、1H NMR、13C NMR(DEPT)、HMQC、HMBC、NOESY]及与文献对照得到了确证。更多还原

【Abstract】 Seven guaiane-type sesquiterpenoids, a new compound 6-formyl-5-isopropyl-3-hydroxymethyl-7-methyl-1H-indene(1), a new natural product 5-isopropyl-3, 7-dimethyl-1H-indene-1-one(2), along with five known compounds: guaiazulene(3), 4-formyl-7-isopropyl-10-methylazulene(4), sesquiterpene ketolactone(5), alismoxide(6) and guaia-1(5), 6-diene(7), were isolated from gorgonian Muriceides collaris collected in South China Sea. Their structures were elucidated on the basis of extensive spectroscopic analysis [MS, IR, 1H NMR, 13 C NMR(DEPT), HMQC, HMBC, NOESY] and by comparison of the spectral data with those of the literatures.更多还原
